Now the problem is that i am running out of memory even though there is much left on the hard disk. It seems to me i am able to use only 4.'File System' which is of 90 GB and i am not abel to use 1. '500 GB Hard disk:100 GB file system' and 2. '500 GB Hard disk:295 GB file system'.

I have used around 88 GB on the whole system now and I keep on getting pop up saying that you are running short of memory. I am not able to download anything now as the download fails for the same reason. Both 100 GB filesystem and 295 GB filesystem are mounted under /media.

How much RAM does the machine have? Also, how much SWAP did you set? Is the SWAP on a separate partition or is 1. '500 GB Hard disk:100 GB file system' 2. '500 GB Hard disk:295 GB file system' - all on one partition? I usually have SWAP on a separate partition and I use at least twice as much disc space per gig of RAM in my PC (i.e. 8 Gb SWAP per 4 Gb RAM), That seems to work quite well on my system. You could probably use 1 1/2 times the RAM as I do for Windows swap space, but I like 2 times the RAM for Linux. It just runs better in my opinion.

I have a 4GB RAM. here are the partition and swap details. Also i can see in nautilus that 1. '500 GB Hard disk:100 GB file system' and 2. '500 GB Hard disk:295 GB file system' are mounted under /media. I am not able to much out of these command results as i am new to linux.roopesh@minto ~ $ sudo fdisk -l[sudo] password for roopesh:

You are running out of storage memory. Move all of your stuff to the other partitions mounted in /media....that will free up space on / after that, look into mounting one of those big drin in media as /home.... good luck.... ram is not an issue.

If it were me, I'd resize the partitions with gparted on the Ubuntu LiveCD so that I'd have enough space to make the "/" dir about 20GB, then I'd create a swap partition of at least 2-2.5x my RAM, then I'd partition the remaining available space for /home.

In your case, It seems like you will need to either resize one of the partitions in media in order to create space for your "/" or create a separate /home partition and copy files onto it (see this article for how to do that: https://help.ubuntu.com/community/Partitioning/Home/Moving ). Just make sure you do a complete backup before making any partition changes because you never know what might happen.

I began getting out of memory messages regarding kNotes even though allpartitions were no more than half full. I noticed that the knotes files hadvery restrictive permissions. I had not changed those, but just toexperiment I changed those and the error messages went away. So, sometimesan app is not carefully written and it reports the wrong error.

Hi roopesh vp,I am very curious about the out of memory pop up you have been seeing in Linux Mint. Can you please tell us the exact wording of the error and title of the window? Usually, when Mint is short on resources, the entire screen will 'grey out' for periods of time while data in RAM is moved to Swap and vice versa.

You mention the hard drives when you say you are out of memory. The problem is, hard drive space is not memory.

Think of your computer as an office. The hard drives are the filing cabinets. They store all your information but you can't access that information since it is in a cabinet. That's what your hard drive does. It holds and stores your information.

Your desk is your memory or RAM. That is where you put your files you have pulled out of your filing cabinet. On your desk, the files and information are visible. You can read them, edit them, and re-arrange them. That's what your memory (RAM) does. It provides a space for your data that makes it usable to you.

Knowing this, an error telling you that your system is low on memory (RAM) is telling you there is not enough space left on your desk. This can happen even though your filing cabinet has plenty of free space remaining. Normally your computer would take some of your data from RAM and store it in a special filing cabinet called Swap.

Swap space is like a to-do box. It's not on your desk but it is easy to get to and has the files you most recently worked on. That's what Swap does. It provides a place to put your data that you aren't using right now but may need again very soon.

So, you will want to find out what is using up your memory. Open up a terminal window and run

top

While top is running press shift+m (capitol M) to sort the output by memory used. Now click edit > select all >edit copy and paste the output in your reply message. This will let us see the Cpu, Memory, and Swap being used. Perhaps we can find the program(s) eating up your memory.

Please be sure to also include the exact text of the out of memory error message, the title of the error window, and let us know what you were doing when the error came up.

Thanks everyone, i could resolve the problem. i just copied files from home folder to media. Its in fact not a RAM issue but hard disk space. Sorry for using a wrong terminology.I tried what mark suggested and it is fine now. A special thanks to William for such a detailed explanation. Thank you so much.

When re-sizing partitions be very careful as it is all too common to damage the boot-loader, thereby causing Linux and/or Windows (or other OS'es) to be unable to boot. Fortunately, Linux makes it fairly simple to remedy this by using the install disc and "repairing the boot loader" (i.e.GRUB or Windows, etc.). This is also a feature of Windows installation discs. I completely agree that a full backup of important data is essential before any changes are made to the partition structure. If the hard disc is a "vanilla" installation and the data has been saved elsewhere, then go for it and re-partition to your hearts content. The suggestions outlined by Shannon Van Wagner are similar to my own scheme and work quite well.
